Landscape Greening Following Unseasonal Precipitation Along a Desert–Alpine Gradient

Christian John, Bradyn O’Connor, Thomas R. Stephenson, Eric Post

In seasonally arid systems, where water is a key limiting resource, unseasonal precipitation events may promote landscape greening. Because herbivores track spatial variation in fresh plant growth, dry-season precipitation could be an important catalyst of out-of-season foraging opportunities in seasonal arid environments. …

Reducing consumer pressure increases community dissimilarity leading to coral‐ or algal‐dominance on a coral reef

Kelly E. Speare, Thomas C. Adam, Allison Aplin, Noe Castañeda et autres

Abstract In many ecosystems, anthropogenic influences are altering the strength of top‐down (e.g., herbivory and predation by consumers) and bottom‐up (e.g., nutrients) processes through the exploitation of consumers and increasing anthropogenic nutrient inputs. Altered top‐down and bottom‐up processes may significantly change ecological …

The SORTEE guidelines for data and code quality control in ecology and evolutionary biology

Joel L. Pick, Bethany J. Allen, Bénédicte Bachelot, Kevin R. Bairos‐Novak et autres

Open data and code are crucial to increasing transparency and reproducibility, and in building trust in scientific research. However, despite an increasing number of journals in ecology and evolutionary biology mandating for data and code to be archived alongside published articles, the …

Terrigenous inputs link nutrient dynamics to microbial communities in a tropical lagoon

Christian John, Nyssa J. Silbiger, Thomas C. Adam, Danielle M. Barnas et autres

Abstract Nutrient availability drives community structure and ecosystem processes, especially in tropical lagoons that are typically oligotrophic but often receive allochthonous inputs from land. Terrestrially derived nutrients are introduced to tropical lagoons by surface runoff and submarine groundwater discharge, which are influenced …

Long‐term community dynamics are heterogeneous between fringing‐ and fore‐reef habitats on an Indo‐Pacific coral reef

Peter J. Edmunds, Christian John, James J. Leichter, Charlotte Moritz et autres

Abstract Benthic community structure on present‐day coral reefs is often described as rapidly degrading, yet such summative statements do not capture the effects of spatial heterogeneity in communities. We focus on Moorea, French Polynesia, where the fore reef has shown high ecological …

Land use shapes riverine nutrient and sediment concentrations on Moorea, French Polynesia

Kyle Neumann, Christian John, Terava Atger, Tauira Punu et autres

Human activities drive changes in freshwater ecosystems by altering biogeochemical cycles. Freshwater networks provide important ecosystem services to human societies by purifying water and serving as an intermediary between terrestrial and marine systems. On high volcanic tropical islands, human activities are compartmentalized …

A framework for reproductive outcomes of phenological match–mismatch in migratory breeders tested on a declining species, caribou

Eric Post, Pernille Sporon Bøving, R. Conor Higgins, Christian John et autres

Long-distance migrants with endogenously timed reproduction may be especially vulnerable to phenological mismatch on summer ranges where offspring are produced and provisioned. In such species, departure timing from winter ranges, and consequently breeding timing on summer ranges, is cued primarily by photoperiod, …
